Gorilla

Gorillas are herbivorous. They live in western equatorial
Africa and are related to chimpanzees but are less erect and much
larger (the largest of anthropoid apes). The big male gorilla in the first
picture was apparently wondering whether he should keep watching those
other smaller, hairless apes, who had been brought by the
hundreds for his entertainment into his zoo in Cincinnati, Ohio, in May
2001. The other two pictures are from the Chicago Brookfield zoo,
in August 1999.
